Slippery Slope U Pick You will need your MSG, whiteboard (& graphing whiteboard), dry erase marker, and a sock/cloth.

U Pick 2 – Draw the Slope 1.) positive 2.) negative 3.) undefined 4.) zero Hey, I wonder what type of slope this branch has?

1.) 3.) 2.) 4.) m=4/3 Pos. m=-4/5 Neg. m=3/2 Pos. U Pick 2 – Count the Slope from Graph & Identify Slope Type m=-3/4 Neg.

U Pick 2 – Find the Slope Using the Slope Formula 1.) (1, 7) and (-1, 6) 2.) (-3, 1) and (3, -1) 3.) (-2, 5) and (-1, 3) 4.) (5, -7) and (6, -4) 5.) (0, 2) and (8, 0) 6.) (-2, 5) and (3, -10) m=1/2 m=-1/3 m=-2 m=3 m=-1/4 Attention: U-Pickers There’s a strawberry in the field at (1, 7) and (-1, 6)! m=-3

U Pick 2 – Write the Equation in Slope-Intercept Form from Graph 1.) 3.) 2.) 4.) y = x + 2 y = 3/2x + 6 y = -1/2x + 2 y = 25x + 100

U Pick 3 – Write the Equation & Identify Slope Type 1.) 2.) 3.) 4.) 5.) y = 3 x = -1 x = 4 Red line? y = -2 Blue line? x = 3 y = -1

U Pick 2 – Find the x and y-Intercepts 1.) 2x + 3y = ) 6y – 3x = 6 3.) 4x – 3y = ) 3x – 2y = 6 5.) 4x – 3y = -9 6.) 11x – 4y = 32 x = -6, y = -4 x = -2, y = 1 x = -15/4, y = 5 x = 2, y = -3 x = -9/4, y = 3 Toaster pastry, you taste so good and yummy. Toaster pastry, get into my tummy. x = 32/11, y = -8

U Pick 2 – Write the Equation in Slope-Intercept Form 1.) m = -2/5; b = 4 2.) m = 4; b = -1/2 3.) m = 2; b = -3 4.) m = 1/4; b = 4 5.) m = -1/4; b = -6 6.) m = 5; b = 0 y = -2/5x + 4 y = 4x – 1/2 y = 2x - 3 y = 1/4x + 4 y = -1/4x - 6 y = 5x
